Be it known that l, Teen/u: Smuonn iVlOitGAN, u, eitizem of the United Smtel'i, residing Pill Chicago, in the county ol ook and State of llliuii is, have invented new and useful Improvements in Stem]1-HontingSystems, of Which the liiillowingr is :1- speriliention.

This invention is n devire or eonihii'mtioi'i for creating and, nuiintnining automatically 1, vacuum in 2L low-pressuresteam heatiru; apparatus. For arious reasons Well knownin the art themaintenance of n 'neuuin in eueh o ipamtus is desirable.

The object ol the present invi-zntion is to do this in on automatic .tiltl ollieient numner. an

will more fully appear from the lollowiup; opeeilieation.

in the lTMCOlllPlilYlIllZ' dmwinge, Figure .l is an elevation illustrating, the system. Fig. :2 1s a diagram of n modification,

Referring specifically to the drowii'igs, 6 indicates the boiler of o. low-preoeure steamlieeting system, of which 7' is the flow and i? the return pi es. lending to radiators (not shown) of any suitable kind. A vacuum steam-pump is indicated at 9 lrom the slzeonn cylinder 10,-the exlniuet from which passes by the pipe ll to the flow-pipe 7.

12 is the suetion-pipe, connected from the pun1p-eylinder 13 to the 'returnpipe ehovo the Wttil'l'dlil oi the boiler 6.

l4 indieutes e hoil'er feed-pump, the suclilOH-PiPQ ll; of which is mnneoted to the pipe R below the wnterdine oi the boiler (:2. This iently o iwrzited. by direct pump 14- is woven with the proton ol' the connection. hy n rod 16 ratcom-cyliruler l0.

17 indicates n sine-ll slnaem-genemtor, and 1E n Weten-regulator which eontrols the supply of Water from the pump lei. to'the generator through the pipe 19. titem'n genmen in. the boiler 17 is conveyed lrv o pipe 20 to the e nun-cylinder 10 to opmnte the pump 9. The pump 14 also hos i dischargepipe 21, leading to the boiler l7.

Gee fuel for the hoilex 17 is furnished through a pipe 252, and the flow or eupplv is controlled es'tollmvs: The diophrnuni-vnlve 23 in the pipe 22 is connected by n pipe 24 to the return-pipe R. A pro-inure inside enid pipe or the lu-sziting' system preeses on the dinnhmoin ol' the valve 23 and holds the valve Specification or" Letters Patent. Application filed September 16. 1905.

also has another din eontrolled by the lopen. The pipe 22 l pl'iragrn valve 55 which is; l temperature of the pipe 8 in the following manner: An ine-losed cylinder 26, oontoinii'ig gri'isolene, other, nleohol, or any other liquid l having a low boiling-point, surrounds the l pipe 8, and when the temperature of the pipe l in raised the liquid 'olutilizes in the cylinder 26 and (routes a pressure Whiehis transmitted through a pipe 27 to the vnlve and keeps l the valve rlosed when the system is hot and open when it is void. The supply oi gas to 17 is thus mimtrolled by both pres l euro and temperature. then the system is l cold and there is an inside pressure therein, [I the valves 23 and are both open, which l l the boiler permits the gas to flow through the pipe 22 to the burner 28 under the boiler 17, Where it is ignited by a pilot-light 29, the supplypipe of Winch is conneeted to the main 22 on. the other side of the valves.

Steam generated in the boiler 17 passes througl'i the pipe 2i) and operates the pump 9, which exhausts air or water and reduees pressure in the heating apparatus, so that the flow proceeds until the desired heat is ohtallied. l Vhen the )ri rssure is reduced to the desired extent, thevnlvo 23 will close and the supply of fuel to the boiler 17, and eonseqnently' the operation of the pump 9, will he stopped. When the pressure rises, the valve Will open-end the pump may he started again; but when the s vstom is hot the Suppl of fuel to thohoiler 17 will he stopped by the valve 2'6, as above described.

Where a supply'of electricity can he used to better ndvnntage than one, the arrange ment shown in Fig. 2 run lw ine'rallm'lv 'l'lmre a motor 30 is substituted for the generator 17 to operate the pump and the dinphrognn switches 23 and 25" for the valves 23 and 25.

It enn be seen from the above that the pump operates only when needed. and then it Works outon'inticnlly in starting und stopping.
